Posteriorly, the soft palate ends as a midline projection called the uvula that projects into the oral cavity.

What is the function of the soft palate quizlet?

It separates the nasopharynx from the oral pharynx and forms a tight seal around the larynx during breathing. However, during swallowing, the soft palate is elevated and closes the posterior nares, protecting the nasal passages from food and water.

What problems can the soft palate cause?

The thesis shows that tissue damage in the soft palate also is an important factor that contributes to the development of sleep apnea and disturbances in swallowing function. “The nerve and muscles injuries seem to contribute to the collapse of the upper airway during sleep.

Throat anatomy

The oropharynx includes your tonsils and the bands of tissue around the tonsils, the soft part of the roof of the mouth (soft palate), the back third of the tongue, and the rear wall of the throat. As you continue down the oropharynx, you reach the laryngopharynx, the space where food and air pass.

How does the soft palate affect the direction of the air stream?

Pull-up of the soft palate moves it both upward and backward; this opens the fauces but narrows the velopharyngeal isthmus, potentially increasing resistance to airflow. Depression of the soft palate has the opposite effects.

Which sound occur at the soft palate?

A velar sound is produce by bringing the tongue back up close to or incontact with the soft palate.

What is soft palate in phonetics?

Soft palate (velum)

The soft palate the soft portion of the roof of the mouth, lying behind the hard palate. The velum performs two important roles in speech: The tongue body hits it in order to make the sounds [k], [ɡ], and [ŋ]. It acts as the “gatekeeper” to the nasal cavity.
